Consider the following statements :

Assertion $(A)$ : The circle ${x^2} + {y^2} = 1$ has exactly two tangents parallel to the $x$ - axis

Reason $(R)$ : $\frac{{dy}}{{dx}} = 0$ on the circle exactly at the point $(0, \pm 1)$.

Of these statements

  • A

    Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

  • B

    Both $A$ and $R$ are true but $R$ is not the correct explanation of $A$

  • C

    $A$ is true but $R$ is false

  • D

    $A$ is false but $R$ is true
